Find a day, did not find a solution, it seems never even met people like me this question. . .
At present only a preliminary study webservice, not use maven! !
So I put all the jar package lib directory cxf are copied directly to the project inside, to prevent the problem dependent error.
But still reported the Servlet with a name javax.ws.rs.core.Application is not available
I really headache

Big brother can hope pointing or two! ! !
